摘要

防晒配方已经被开发出来，为人类过度暴露在紫外线(UV)辐射下的有害影响提供人工保护屏障。近年来，超快泵-探针光谱技术已成为确定防晒霜配方中活性成分光化学的宝贵工具，主要是紫外线过滤器，在气相和溶液相中。这些测量能够阐明分子松弛途径和光保护机制，这反过来又对评估滤光片的光稳定性和防晒霜使用的适用性有深刻的见解。在这篇综述中，我们讨论了自下而上方法的好处:从真空中防晒紫外线过滤器的研究进展，远离任何溶剂的影响;在解决方案中，研究潜在的防晒霜过滤器在更接近现实生活条件下的松弛途径，同时探索选择性功能化的优点，以改善其特性;除此之外，目前的进展是模仿将防晒霜配方应用于皮肤表面。

Applications of ultrafast spectroscopy to sunscreen development, from first principles to complex mixtures

ABSTRACT Sunscreen formulations have been developed to provide an artificial protective barrier against the deleterious effects of overexposure to ultraviolet (UV) radiation in humans. Ultrafast pump-probe spectroscopy techniques have been an invaluable tool in recent years for determining the photochemistry of active ingredients in sunscreen formulations, predominantly UV filters, in both the gas- and solution-phases. These measurements have enabled the elucidation of molecular relaxation pathways and photoprotection mechanisms, which are in turn insightful for assessing a filter's photostability and suitability for sunscreen use. In this review, we discuss the benefits of a bottom-up approach: the progression from the study of UV filters for sunscreens in vacuum, away from the influences of any solvent; in solution, to investigate the relaxation pathways of potential sunscreen filters in closer to real-life conditions, whilst exploring the merits of selective functionalisation to improve their characteristics; and beyond, to current advances that are mimicking the application of sunscreen formulations to the surface of the skin.
